1. One of the main purposes of aluminium-silicon coated steel is to replace galvanized products, so aluminium silicon coated products have the
same mechanical properties, dimensional accuracy and plate shape control with galvanized products.
2. Because the density of aluminium-silicon is lower than that of zinc,
the coating weight can beless
by using aluminium-silicon coated products instead of glavanized products.
3. Aluminium-silicon coated products have
excellent corrosion resistance, several or even a dozen times
than that of galvanized products.
4. Aluminium-silicon products have
good high temperature resistance,
therealmost
isn't any change
evenduring long-term use
below 550ºC.
The steel plate with aluminium-silicon coating will
maintainthe bright appearance
.
5. Aluminium-silicon has
excellent heat reflectivity,
with a
light reflectance of about 80% when the temperature below 500 ºC.
6. The friction coefficient of aluminium-silicon coated products is lower, and
low friction coefficient is favorable for drawing andforming.
